Concerns over food adulteration continue to grow as households increasingly rely on packaged spices, dairy products, and processed ingredients, prompting many consumers to question the purity and authenticity of everyday kitchen staples.

Addressing this issue, Qatar-based food safety officer and content creator Ahana Nazar Hafis recently shared simple at-home methods to help identify possible adulteration in commonly used ingredients. She explained that food adulteration refers to the addition of unwanted or foreign substances to food, whether done intentionally or unintentionally, which can compromise both quality and safety.

One of the simplest checks she suggested is the turmeric test. In this method, a small amount of turmeric powder is added to a glass of water and observed closely. If the powder releases a bright yellow colour immediately and spreads rapidly, it may indicate the presence of artificial dyes. In contrast, pure turmeric typically settles at the bottom without quickly colouring the water, which remains relatively clear.

For chilli powder, Ahana recommends a similar water test. When a small quantity is added to a glass of water, pure chilli powder tends to settle slowly. However, if the red colour spreads rapidly through the water, it can be a sign that synthetic colouring agents have been added to enhance appearance and vibrancy. This test is often used by consumers concerned about the quality of commercially sold spices.

Another commonly discussed issue is milk adulteration, particularly dilution with water. According to the method shared, a drop of milk placed on a smooth, slanted surface can help indicate purity. Pure milk is expected to flow slowly while leaving behind a white trace, whereas diluted milk tends to move quickly without leaving any visible trail.

Finally, she highlighted a simple test for tea powder. Adding a spoonful of tea to cold water can help indicate purity. If the water remains largely colourless, the tea is likely unadulterated. However, if the water quickly begins to change colour, it may suggest the presence of added dyes used to enhance appearance.
